How To Prepare For Winter
Don't Get Stranded In The Cold

 

For most of us, by the time this issue hits your mailbox, winter will be looming on the horizon. Sub-freezing temperatures. Snow. Ice. Blizzards, Nor' easters, 30 inches of standing snow. Not pleasant weather to be working on the Jeep. Even worse, it's dangerous weather to be stuck in a broken-down Jeep.

Now is the time to do your maintenance for the winter. Whether or not you take your Jeep wheeling in the winter, breaking down for a simple maintenance item is not only dumb but dangerous. We've compiled this checklist of the more common items so that you'll be well-prepared when winter rolls around shortly. Remember, your Jeep will likely have special needs that you'll have to keep in mind, but this will get you going.

Maintenance - (What to do before it's cold)

1. Make sure your cooling system is in good shape. If you are in doubt about the mixture of antifreeze to water in it, drain the liquid and replace it. Also, if the coolant has been in there more than a year, drain and replace it too. Believe it or not, snow driving is hard on the cooling system, and you want everything working in top form. Between higher rpm, higher engine loads, and the occasional snow jammed in the radiator, the system has its work cut out.

2. Check hoses while you are messing with the cooling system. Check them for bulges, cracks, or anything out of the ordinary. If there is any doubt, replace them. Heat-cycling in the cold is rough on rubber, and if your stuff is worn then it's that much more likely to burst.

3. Get under the Jeep and grease everything with a zerk fitting.

4. Check driveshafts for play. Do this while the Jeep is out of gear with the wheels chocked on level ground. If any of your U-joints are going bad or seem questionable, replace them.

5. Check your accessory drivebelt(s). If any are cracked or glazed, replace it and keep the old one under the seat as a spare, just in case.

6. If you drove your Jeep during the spring or summer, check your axles, transmission, and transfer case for water. Just look for chocolate or strawberry milk shakes, especially if you've done any stream, river, or pond crossings, you should replace those fluids.

7. If you swap to winter tires, now is the time to do it. If not, check tires for wear, dry rotting, and tread depth. Anything under 11/44-inch is dangerous in the winter and should be replaced.

8. Lubricate all door and tailgate locks with a good graphite lock lubricant, not WD-40 or anything else oil-based. The inside of the locks will attract dirt, which will attract moisture, which freezes

9. Spray the rubber door, tailgate, liftgate, and even hood seals with a silicone-based spray. If rain, sleet, or snow finds its way to your seals and then freezes overnight, you'll have problems getting into your Jeep or, in some cases, be locked out entirely.

10. Check clutch and brake fluids. If they are really dirty, it means there is a lot of moisture in them. Have them power bled or get a friend to help. Get new, clean, moisture-free DOT 3 or DOT 4 fluid in there.

11. Brake pads and shoes. Now is the time to make sure they are OK. Don't wait until after the first blizzard to check.

12. Emergency/parking brake: Make sure the cables are OK (no rust, fraying, or anything), and the system works as it's supposed to.

13. Any electrical connections that are subject to the weather - such as headlights, turn signals, stoplights, winch cable controller, electric fan connectors, and the like - should get some dielectric grease applied to them. If they use road salt where you are or where you go, the connections will corrode much faster in the winter and, in some cases, cause other problems.

14. If it gets really cold where you live or you drive in really sloppy conditions, get some of the "winter" windshield washer fluid. Drain your washer reservoir either through use or other means and run your washer pump for 10-15 seconds to get the summer

swamp water (or whatever was in there) out of the lines from that last mudding trip.

15. Vent lines are easy to forget in the winter. But once you get done driving down the highway to the trail and you start plowing your axles through the snow, the vent lines will rip out if they aren't attached firmly. If they aren't in good shape or attached at all, the melting snow will find its way in as the hot axle cools. Granted, snow alone probably won't hurt, but one dunk in that frozen lake or ice-water stream could mean a world of hurt for your expensive gears and lockers.

Jeep Gear - (stuff to carry for your Jeep)

1. Radiator hose repair kit, with the correct size tube for the upper and lower radiator hose as well as the heater hoses.

2. Spare accessory drivebelt(s).

3. Coolant.

4. Rain-X (in case of wiper failure - won't help once they put down salt or sand though).

5. Extra windshield-washer fluid, either in a spray bottle or a gallon bottle.

6. Rags.

7. Fire extinguisher.

8. Road flares or emergency triangles.

9. Duct tape.

10. Tire chains or studs, if they are legal where you live.

11. Fix-a-flat tire inflator/sealer - the tire shop will hate you for it, but it beats having to change the tire in a blizzard.

12. Spare tire, jack, and lug wrench (just in case the fix-a-flat doesn't work).

13. Shovel. A collapsible entrenching tool doesn't work well in the snow, don't ask us how we know. Get the biggest shovel you can fit in your Jeep, and if it's a snow shovel, make sure it's really heavy-duty.

14. Strap, D-ring shackles, winch controller, whatever you'd bring normally on the trail to get unstuck, bring it out in the snow, even if you are just driving to work.

People Gear - (to carry in the Jeep for you)

1. Survival gear.That means sleeping bags, space blankets, warm jackets, gloves, hats, dry socks, and a change of pants. Get in the habit of storing at least a heavy jacket or polar fleece in the Jeep as well as a wool hat and warm gloves. Take the other stuff for longer trips.

2. Water. Yeah, it'll be tough keeping it warm once the Jeep dies, but keep it in smaller containers or bring smaller containers and keep it close to your body under your heavy outerwear. Dehydration danger is very real in the winter because really cold air is often really dry air, and you don't notice thirst like this when it's hot. Digging out your Jeep while stranded in the middle of nowhere means you'll need water.

3. Iodine tablets or water filter. For those long trips into nowhere, these don't take up any space and will give you potable water wherever you can find it thawed enough to drink.

4. Flashlight with extra batteries. Even better, an LED flashlight with extra batteries. The light will always die on you when you need it. Have fresh batteries with you.

5. Navigational tool. Whether it's a state-of-the art GPS unit or a simple map and compass, learn how to use whatever you bring before you go. If it's a GPS, you guessed it, bring extra batteries.

6. Something to make fire with. Lighters are good because they can light so many more fires than matches. Trouble is, you never know when it's going to die. The flint could go at any time, as could the remaining fluid. Matches, you always know how many you've got, but they are more susceptible to moisture than a lighter is. My choice, a Zippo lighter. Keep two extra flints in the bottom between the first and second layer of cotton and carry extra fuel. Even on short trips, this is something you should have.

7. Food. Granola bars, oatmeal, or just about any non-chocolate energy bar are easy to store in a Jeep. Throw them in, and forget them for the winter.

8. Communication device. Ham radio, CB, and/or cellular phone, are all decent choices. The battery rule applies here too, if its not hard-wired into the Jeep.

A Last Minute Thought

Tell someone where you are going and when you'll be back. As dependent as we are on our technology, it's easy to forget this time-honored technique.

 

 

blankets (being cold sucks), a snow-friendly shovel (big scoop, not the little military issue ones that's good in dirt), recovery equipment, spare tools, always keep 1/2 tank or more of fuel (helps keep you warm waiting for help, and with weight), and some food and bottled water (keep under the seat so it thaws as you're driving along so if you get stuck you don't have a bottle of ice way in the back of your jeep). With that, you should be ready for a day or two stuck in the snow.

you can get a recovery kit at the GLXJ store (see way at the top of the webpage), and with the prices of the components individually, it's a pretty good deal.

...and make sure your Jeep is in good running condition (see Adam's post).

One thing some may want to check out, Harbor Freight has a plug in 12V heater for like 9.99. My brother has one he uses until his truck warms up, seems to work pretty well. Only about 6 or 8" wide. Would be good for if the gasoline runs out or the truck won't start. Can't take that much power to run it.
